Of those four, only Bonner stands a significant chance of coming back. The Spurs value his unique skill set as a 3-point shooting center/forward, which they could be hard-pressed to find on the free-agent market.

Bonner's agent, Kenny Grant, said formal talks with the Spurs have not yet begun, but he expects them to start soon.

“Matt wants to be a Spur, and I'd imagine they want him back, too,” Grant said.

The Spurs are open to bringing back Bonner, but only if the price is right.

A career 40.5 percent shooter from 3-point range, Bonner made $3.2 million last season. He averaged 7.0 points and 3.3 rebounds and shot 39 percent from 3-point range, despite missing 17 games after breaking his hand in December.

WELCOME BACK: Former Spurs point guard Jacque Vaughn is expected to serve as an assistant coach for the team's summer league squad next month in Las Vegas, an endeavor he might hope to parlay into a full-time gig next season.

The Spurs are in search of a replacement for long-time assistant coach/head video coordinator James Borrego, who left after seven seasons to join Monty Williams' new staff in New Orleans.

Vaughn, who spent the final three of his 12 seasons with the Spurs, retired after the 2008-09 campaign. He has long been held in high esteem by coach Gregg Popovich, who has called Vaughn prime coaching material.
